William, your link is broken. You have a good link?

The "Like other types of data and cell formatting" is no longer true. You can now apply character formatting (bold, italic, underline, etc) to any number of characters in a cell, rather than all characters. The same "should" be true for hyperlinks, but isn't :-]

It's hard to believe it's 5 years on and such a crucial feature is still missing from Google Spreadsheets.

For me, all of a sudden, hyperlinks within a cell full of other text are suddenly behaving and looking like hyperlinks! But Sheets randomly decides when it can recognise them because other cells in the same column are still treating the hyperlinks that they contain as if they are plain text.
